England's Prince Harry Takes the Plunge

Prince Harry turned daredevil Wednesday and spent some of his spring break from school rappelling 200 feet down a wall to raise money for charity, PEOPLE reports from its London bureau.

The redheaded Harry, 18, who is third in line to the British throne, was among a group of 80 roped-up volunteers leaping down the side of a wall at the historic St. Bartholomew's hospital in London.

"It was a good laugh and all for a good cause," the young royal said after taking the plunge.

Specifically, he was raising money for a mental health charity, the Winfield Trust.

This isn't the first time Harry has been in the news for his adventures. In 1998, his watchers were criticized for letting the then 13-year-old prince rappel down the side of a dam in Wales without wearing a helmet.

Harry is on his last vacation before he finishes studies at the prestigious private school Eton College, where he'll graduate in June.

Palace sources will not confirm to PEOPLE what he plans to do next, but there is speculation that he will take a year off (like his brother Prince William, 20, did) before heading into the armed forces or on to college.
